1. What Half-Inderal LA 80 mg is and what it is used for
Half-Inderal LA 80 mg contains a medicine called propranolol
hydrochloride. This belongs to a group of medicines called betablockers.
Half-Inderal LA 80 mg is used for many conditions including:
• High blood pressure (hypertension).
• Chest pain (angina).
• Preventing migraines.
• Essential tremor (shaking with an unknown cause).
• Anxiety.
• Some thyroid problems (such as thyrotoxicosis which is
caused by an overactive thyroid gland).
• Bleeding in the food pipe (oesophagus) caused by high blood
pressure in the liver.
It works by the effects it has on the heart and circulation and also
on other parts of the body.

Do not take Half-Inderal LA 80 mg if:
• You have ever had asthma or wheezing. If this applies to

or any of the other ingredients in Half-Inderal LA 80 mg (see
section 6: Further information).
• You have ever had any of the following heart problems:
- heart failure which is not under control (this usually makes
you breathless and causes your ankles to swell)
- second- or third-degree heart block (a condition which may
be treated by a pacemaker)
- very slow or very uneven heart beats, very low blood
pressure or very poor circulation
- a type of chest pain (angina) called Prinzmetal’s angina.
• You have a tumour called phaeochromocytoma that is not
being treated. This is usually near your kidney and can cause
high blood pressure.

acid in your blood (metabolic acidosis).

If you are not sure if any of the above apply to you, talk to your

Taking other medicines
Please tell your doctor or pharmacist if you are taking, or have

medicines work and some medicines can have an effect on HalfInderal LA 80 mg.
In particular, tell your doctor if you are taking any of the following
medicines:
